Abstract

Kawasan pinggiran kota Malang merupakan salah satu fenomena dari proses urbanisasi yang disebabkan oleh industri. Beberapa faktor yang mempengaruhi seperti jumlah penduduk, kepadatan dan tingkat migrasi, hal tersebut berdampak pada peningkatan luas lahan terbangun. Selain itu, perubahan lahan juga disebabkan ole ketidak seimbangan antara permintaan fasilitas dan lahan perkotaan sehingga kecenderungan masyarakat untuk tinggal di kawasan pinggiran meningkat. Oleh karena itu konsekuensi fenomena ini akan terjadi perubahan lahan di kawasan pinggiran. Berdasarkan latar belakang tersebut, maka penelitian ini fokus pada indetifikasi karakterisik perubahan lahan di kawasan pinggiran kota Malang. Penelitian ini menggunakan metode kuantitatif dengan beberapa tahap yaitu (1) melakukan deliniasi kawasan pinggiran yang memiliki tingkat perubahan tertinggi (2) mengidentifikasi karakteristik perubahan lahan. Hasil dari penelitian ini menunjukkan bahwa (1) kawasan pinggiran tertinggi terletak di kecamatan Karangploso, kecamatan singosari dan kecamatan pakis. (2) hasil penelitian selajutnya menunjukkan bahwa bahwa jumlah penduduk, migrasi, dan perubahan mata pencaharian berbanding lurus dengan perubahan lahan sedangkan tingkat kepadatan berbanding terbalik dengan perubahan lahan Deskripsi Alternatif :In suburban of Malang city as the one of the phenomenon of urbanization process which caused by industry activity. It influence three factors i.e. population, density and migration that creates the expansion of built up area between urban to suburban area. In addition, the land use change is also caused by the imbalance between the demand for facilities and urban land use, so the tendency of society to live in suburban area is high. Thus the consequences of this phenomenon will be occurs land use change in suburban area.

Abstract

This paper introduces two advantages of a fuzzy logic controller for the first is stability voltage and the second is maximum energy extraction for fixed speed wind power generation systems. Maximum energy extraction is determined by thetip speedratio (TSR) and the power factor of a wind turbine in order to capture the maximum efficiency and control the speed of turbine in order to control voltage stability.While the TSRand power factor were taken as output variables we propose control the tip speed of generator in surrounding the value of maximum TSR. The proposedmodel produced fuzzy logic controller can keep the voltage stability at maximum TSR and nearest. The results indicate that we can do two task (power max extraction and stability voltage) in one design.

Abstract

Setiap atlet yang akan menghadapi suatu pertandingan dalam berbagai even pertandingan, dalam keadaan cemas karena berbagai tekanan yang menjadi beban bagi dirinya. Kecemasan berdasarkan pengelompokannya ada kecemasan bawaan, dan ada juga kecemasaan yang sesaat. Kecemasaan bawaan lebih mendapatkan penanganan yang agak sulit karena sudah bawaan, sedangkan kecemasan sesaat dapat dilakukan dengan berbagai penanganan yang lebih mudah dibandingkan kecemasaan bawaan. Kecemasan sesaat masih dikelompokkan lagi dalam kecemasan cognitive dan kecemasan somatic. Banyak hasil penelitian mengungkapkan kecemasan somatic yang banyak cenderung berpengaruh pada atlet ketika menjelang pertandingan dibandingkan dengan kecemasan kognitif.

Abstract

Watermelon rind water extract contain of citrulline. Citrulline is a precursor of generating Nitric Oxide (NO). NO possibly reduced the level of blood glucose in reptozotosin-induced diabetic rats. This study was a laboratory experimental study completely randomized design. A number of 30 male albino Wistar rats weighting 100-200 gr were devided into six groups (N=5), with group 1 served as normal control group. The other groups were given streptozotosin to induced diabetes mellitus. The rats in control diabetic group were given CMC 0,5%, the others were given watermelon rind extracs for 8 days with different doses for each group. The results showed that serum glucose levels in posttest control group was significantly different, from that group of the watermelon rind extract 250 mg/kg bw/day (p = 0,000), groups of watermelon rind extract 500 mg/kgbw/day (p = 0,000) and groups of watermelon rind extract 1000 mg/kgbw/day (p = 0,000). The level of triglyceride in postest control was significantly different from that group of the watermelon rind extract 250 mg/kg bw/day (p = 0,000), groups of watermelon rind extract 500 mg/kgbw/day (p = 0,000) and groups of watermelon rind extract 1000 mg/kgbw/day (p = 0,000). The conclusion, the watermelon rind water extrac can be used to reduced glucose serum level (250, 500, 1000mg/kg bw) with the optimal dose was 500 mg /kgbw/day with the optimal dose was 1000 mg /kgbw/day.

Abstract

Orang menggunakan bahasa untuk mengekspresikan apa yang mereka rasakan atau inginkan. Sebagai contohnya; orang lebih sutra berbicara bahasa asing tertentu untuk menunjukkan pengetahuan dan mendapatkan apa yang mereka inginkan. Di dalam suatu Negara yang mane memiliki banyak budaya dan suku-suku bangsa seperti di Indonesia merupakan hal yang biasa ketika orang menggunakan lebih dan dua bahasa dalam percakapan keseharian mereka. Ketika mereka melakukan hal ini, make mereka menggtmkan campur kode dan alih kode. Penelitian ini membahas fenomena-fenomena campur kode dan alih kode yang digunakan oleh guru-guru Bahasa Inggris terhadap pare siswa mereka di kelas. Ada beberapa alasan mengapa peneliti memilib guru Bahasa Inggris sebagai subyek penelitian. Alasan pertama yaitu;Guru Bahasa Inggris adalah orang yang ahli dalam berbahasa Inggris dan di harapkan menjadi model dalam penggunaan Bahasa Inggris dalam percakapan sehari-hari, khususnya dalam kegiatan di kolas. Ke¬2 yaitu fenomena campur kode dan alih kode yang dilakukan oleh guru-guru Bahasa Inggris balk yang terjadi dengan sengaja ataupun tidak sengajar di SMAN 16 Surabaya belum direliti sebelumnya. Lebih-lebih, peneliti juga sangat ingin tahu tentang alasan guru-guru Bahasa Inggris menggunakan campur kode dan alih kode dalam proses pembelajaran di kelas. Hasil dan penelitian ini menunjukkan bahwa jenis-jenis campur kode yang digunakan oleh guru-guru dikelas adalah dalam bentuk kata dan frase. Sedangkan alih kode dilakukan dalam bentuk lcalimat-kalimat, klausa-klausa, ataupun kalimat sanggahan. Alasan mereka menggunkan campur kode dan alih kode adalah untuk membuat siswa lebih memahami materi yang disampaikan dalam bahasa inggris dan utnuk menghindari terjadinya konsep yang salah dalam pembelajaran tata bahasa dalam Bahasa Inggris.

Abstract

Based on the researcher’s observation to students of mathematics education department ofUNIPA Surabaya, the material of graph theory taught in mathematics discrete course was adifficult course to be understood by the students coherently and deeply. To acknowledge the reasonthat caused the material of graph theory difficult to understand and to improve result of learningmathematics, was needed to conduct error analysis. The analyzed error covering the area and thetype as well as error-causing factor, was done by the students to complete graphic theory question.After recognizing the position and kind of error as well as the causing factor which was conductedby the students in completing the question of graph theory, we can determined its alternativesolution. The research type done by the researcher was descriptive. The research was done inUNIPA Surabaya. The core instrument in this research was the researcher itself, as the researcherwho planned, arranged, conducted, collected data, analyzes data, concluded and made theresearch report. The other instruments in this research were diagnostic test and interview manual.In this research, the data analysis technique was done through three stages, they are : datareduction, data presentation and conclusion. The error area done by the students of UNIPASurabaya of academic year 2010 to complete the problem of graph theory was in problem ofunderstanding, namely the inability to correlate the relation between information and problemsolving which has many misconception. The kinds of error done by the students of UNIPASurabaya of academic year 2010 to solve the graph theory were kind of principle error because itrelated to the error of understanding and implementing theorem as well as definition. The errorcausingfactors done by the students of UNIPA Surabaya of academic year 2010 to solve theproblem of graph theory generally was the lack of accuracy and not having the understanding oftheorems and definition to solve a problem. Based on the area, kinds, and factor caused the errorwhich was done by the students of UNIPA Surabaya of academic year 2010 to solve the problem ofgraph theory so that the alternative model of learning in which the researcher proposes is themodel of meta-cognitive learning.
